Instructions

1. 1

   Marinate the chicken with yogurt, lemon juice, turmeric, and 8 g salt in a bowl. Mix thoroughly so every piece is coated, then rest for 20 minutes at room temperature or 2 hours in the refrigerator for deeper flavor.

2. 2

   Make the roasted spice paste: heat 30 ml oil in a small pan over medium heat. Add coriander, fennel, cumin, peppercorns, dried chilies, cinnamon, cardamom, cloves, star anise, and poppy seeds, and roast for 2–3 minutes until fragrant and slightly darker, stirring constantly to prevent scorching.

3. 3

   Add the desiccated coconut to the same pan and roast for 1–2 minutes until light golden. Remove immediately to a plate to stop carryover browning, because burnt coconut will make the curry bitter.

4. 4

   Blend the roasted spices and coconut with 120 ml water into a smooth, thick paste. Scrape down the blender once or twice so the peppercorns and whole spices fully break down, giving the gravy a cohesive texture.

5. 5

   In a heavy pot, heat 30 ml oil over medium-high heat and add mustard seeds. When they begin to crackle, add curry leaves and stir for 10 seconds to perfume the oil without burning the leaves.

6. 6

   Add sliced onions and cook for 8–10 minutes until deep golden, stirring often and scraping any browned bits from the bottom. This browning is essential because it balances the pepper heat with sweetness and gives the curry its roasted backbone.

7. 7

   Add ginger-garlic paste and cook for 60–90 seconds until the raw aroma fades. Stir in chopped tomatoes and Kashmiri chili powder, then cook 5–6 minutes until the tomatoes soften and the oil begins to separate at the edges.

8. 8

   Add the marinated chicken and sauté for 5 minutes, turning pieces so they pick up the masala and lightly sear. This brief roast in the pot concentrates flavor and prevents the chicken from tasting boiled.

9. 9

   Stir in the roasted spice paste and cook for 2 minutes, keeping the heat at medium so the paste does not stick. Add 300 ml water, bring to a gentle boil, then reduce to a steady simmer and cover.

10. 10

    Simmer for 20–25 minutes, stirring every 5 minutes, until the chicken is tender and the gravy thickens to a spoon-coating consistency. Taste and add up to 4 g additional salt, then finish with cilantro and rest the curry 10 minutes off heat so the pepper and roasted spices round out.
